Everyone makes mistakes, the important part is to learn from it.
As a child I had a lot of doubts if all this was real or not, for an example…
When I was 15 years old I did a ritual to dedicate myself to Lucifer and the second I finished it I mean the absolute very second, there was a picture of me as a baby standing on the window sill falling down. The window was not open and the frame stood stable. I checked all of the reasons for it to fall down and I didn’t find anything. I felt a really powerful energy filling the whole room up and the very next day I heard a voice after waking up.
The more deeper I got the more I knew, it’s me being either crazy or realizing that there’s so much things around us that most of us have no idea of.
Sometimes I became frustrated just like you and sometimes I was sad. I haven’t doubted the reality of the occult for years now and it’s okay to doubt because I personally believe it’s something we all do sometimes in life, especially when you’re a beginner because there’s so much things you need to learn. You did nothing wrong, you created a post based on your emotions and anger is a powerful emotion. The very best part of this is that you learned and now understand it. I hope your personal reasons for your anger has calmed down and that you’re not dealing with whatever you dealt with.
